Multiple lines of evidence support the hypothesis that cladogenesis
and anagenesis occurred within the human lineage after the initial split between the human and chimp lineages.
Endemic species may arise by any of several evolutionary mechanisms, including local cladogenesis
and extinction throughout the rest of a geographic range.
Nevertheless in the above-mentioned, the study of the morphometry as such, does not lead, in great measure, to the establishment of a strong form homology, since according to VILORIA (2001), the labial palpi could have been originated in a multiple and independent way in the Rhopalocera cladogenesis
irresolution due to a lack of data, rather than 'hard' polytomies which is an assertion of simultaneous cladogenesis
(Coddington & Scharff 1996).
Casting species as individuals does not privilege cladogenesis
Later developments in the statistical analysis of nonrandom cladogenesis
have included relative rate tests of diversification (Sanderson and Donoghue 1994), skewness tests of tree topologies (Slowinski and Guyer 1989), and effects of varying rates of cladogenesis
on phylogeny reconstruction (Nee et al.
Biogeography of Triassic tetrapods: evidence for provincialism and driven sympatric cladogenesis
in the early evolution of modern tetrapod lineages.
Hypotheses: We anticipate multiple origins of lichenicolous fungi, partial parallel cladogenesis
, and Gondwanan origin for the Cladoniaceae, but current patterns of distribution are probably partly explained by recent dispersal.
Within the Zingiberales, such a study has been conducted for the family Costaceae (Specht, 2005) where dense species-level sampling across the family includes molecular data for each taxon so that branch lengths could be estimated and a molecular clock approach used to develop age estimates for each of the major bifurcations indicating diversification events in the form of cladogenesis

importante en el Pleistoceno tardio de America del Sur (Soibelzon et al.
Labile ecotypes accompany rapid cladogenesis
in an adaptative radiation of Mandarina (Bradybaenidae) land snails.
Molecular evidence suggests that cladogenesis
